My 99' Jeep Grand Cherokee Thermostat keeps going up and down. Any Help?

Hello. I have a 1999 Jeep Grand Cherokee and everytime I drive my tempature thermostat keeps going up and down. Maybe I need a new one? I'm not sure. I just had my radiator replaced and now i see coolant leaking under the car. I didn't change the thermostat when I had got the radiator replaced. and the heat still works when the thermostat goes all the way down. Please help

Sounds like either the thermostat is sticking, or the radiator is low on fluid. You said you can see where it is leaking, that is where I would start. Bring it back to the place that installed the radiator.
